    Do not run effects during WM startup
    
    When we first start up, we do not want to run effects on any pre-exising
    windows (this is either the case we are starting up and there are no windows,
    or we are replacing an exisint window manager, or worse, we crashed, and we
    just want to get to the desired desktop as quick as possible).
    
    Dithered about where to place the check; putting into the plugin manager
    reduces the number of places (and files) in which it needs to be done.
